# msl - Mercury SICStus Prolog Linker.
|
|
#
|
|
# Loads SICStus object files (*.ql) together with the Mercury library
|
|
# into the SICStus interpreter, and then saves the state to produce an
|
|
# executable binary.
|
|
#
|
|
# Usage: msl [<options>] files...
|
|
# Options:
|
|
# -v, --verbose
|
|
# -d, --debug
|
|
# -o, --output
|

# Environment variables: MERCURY_SP_LIB_DIR, MERCURY_SP_LIB_OBJS
